TECHNICAL FIELD

The present disclosure relates to analytical toilets. More particularly,it relates to analytical toilets that seal the bowl to performanalytical tests and for cleaning.

BACKGROUND

The ability to track an individual's health and wellness is currentlylimited to the lack of available data related to personal health. Manydiagnostic tools are based on examination and testing of excreta, butthe high cost of frequent doctor's visits and/or scans make theseoptions available only on a very limited and infrequent basis. Thus,they are not widely available to people interested in tracking their ownpersonal wellbeing.

Toilets present a fertile environment for locating a variety of usefulsensors to detect, analyze, and track trends for multiple healthconditions. Locating sensors in such a location allows for passiveobservation and tracking on a regular basis of daily visits without thenecessity of visiting a medical clinic for collection of samples anddata. Monitoring trends over time of health conditions supportscontinual wellness monitoring and maintenance rather than waiting forsymptoms to appear and become severe enough to motivate a person to seekcare. At that point, preventative care may be eliminated as an optionleaving only more intrusive and potentially less effective curativetreatments. An ounce of prevention is worth a pound of cure.

At present, there is no easy, hands-off way of measuring human wasteweight, volume and density. While each can be done, there is no knowautomated method integrated in a toilet. Weighing an entire toilet isdifficult and traditional toilets do not hold the entire urine event inthe bowl, so the best that can be done is to measure the weight of aperson before and after using the toilet. This could measure totalexcreta mass, but there would be no distinction between liquid and solidwaste. Also, when you are measuring a small change in weight from a muchlarger weight (like the weight of waste compared to the weight of anadult) the measurement will typically be less accurate.

Exemplary Embodiments

The present disclosure relates to a toilet with a bowl and seatsupported by a frame. The frame includes at least one lifting mechanismadapted to raise and lower the seat and/or bowl. In some embodiments,there may be separate frames for supporting and adjusting the seat andfor supporting and adjusting the bowl. Preferably, the lifting mechanismis further adapted to change the angle of the seat.

In a preferred embodiment, the toilet comprises a motorized seat liftthat is integral with and internal to the toilet. It also providescustomized lifting motions set to individual user's preferences. Thedisclosed toilet looks and feels like a conventional toilet and can helpprevent fall by keeping a person more supported during a lift and helpthem to their feet at a height appropriate for the individual.

In a preferred embodiment, the adjustable frame allows the toilet to beboth shorter and taller than conventional toilets. This makes the toiletmore comfortable and easier to use for both tall and short users,including children, without the need for special stools or spacers.

In various exemplary embodiments, the bowl is supported by a frameincluding at least one actuator. In various exemplary embodiments, theseat is supported a frame comprising at least one actuator. In variousexemplary embodiments, the frame comprises two, three, four, or moreactuators for the bowl and/or seat. In a more preferred embodiment, theframe comprises three pairs of actuators to move the seat. Preferably,the actuators are controlled by a digital controller that coordinatesthe actions of the actuators to thereby provide a smooth lifting andlower at the desired speed. More preferably, the controller isprogrammable, so that users can program the lifting and lowering of theseat to their preference. Even more preferably, the toilet includes auser identification module, so that the user is automatically identifiedas he or she approaches or sits on the toilet.

Referring to FIG. 1, an exemplary embodiment of a toilet is shown with aclosed lid 101, lowered foot platform 120, and retracted handles 210.FIG. 2 shows the toilet with an open lid 101, raised foot platform 120,and extended handles 210. In a preferred embodiment, handles 210 areadapted to be readily ripped by a user, especially while sitting orrising. In a preferred embodiment, the handles 210 move while the seat200 is lowering and lifting a user to enable them to grip the handles210 and use them for support during sitting and rising. The toilet isenclosed with a shroud 400.

In various exemplary embodiments, the shroud 400 covers all the internalsupport components that comprise the frame as well as the bowl 300(i.e., the bowl is covered except for the top that would be covered by alid). In preferred embodiments, the shroud 400 comprises at least onesections of articulated or flexible (e.g., elastic, material) assembledsuch that the shroud 400 can contract or expand as the frame 110 movesthe bowl 300 and/or seat 200. Other sections of the shroud may be rigid.In various exemplary embodiments, the at least some portions of theshroud are removable or openable to allow access to the interior of thetoilet frame. The interior of the toilet frame may include, among otherthings, plumbing connections, fluid supply lines, support structures,health and wellness assessment devices, electronic circuits, digitaldevices (e.g., processors, memory), storage tanks, and communicationmodules. In various preferred embodiments, cover 102 opens to allowaccess to the interior of the frame.

In various exemplary embodiments, the shrouds 400 are preferablydesigned for aesthetic and other purposes. For example, the shrouds 400can be made in various colors to suit the décor of the bathroom thetoilet is installed in. Besides colors, the shrouds 400 can includepatterns or graphics so that the toilet 100 “makes a statement” in thebathroom.

In various exemplary embodiments, the handles 210 include at least onebuttons, switches, sensors, etc. through which the user may control theseat, including, but not limited to, starting and stopping the seat 200,reversing seat movement direction, adjusting the position or angle ofthe seat 200, and adjusting the height of the bowl 300, seat 200, orfoot platform 120.

In various exemplary embodiments, the handles 210 may include at leastone health and wellness sensors. The sensors may be used to measure howhard the user is gripping and provide feedback to the lift control. Forexample, if a user suddenly increases their grip it is likely that theyare struggling with standing or with their balance. Grip pressure mayalso be tracked over time. The sensors may also include detection forheart rate, body temperature, hand health indicators, light sensors,electrocardiogram, pulse, blood test (e.g., using a finger prick), etc.Toilet handles with health and wellness sensors are disclosed in U.S.Patent Pub. No. 2018/0084959, the entire disclosure of which isincorporated herein by reference in its entirety.

Referring to FIGS. 3 and 4, an exemplary embodiment of a toilet 100 isshown with various seat elevations. The toilet 100 includes a frame 110,bowl 300 supported by the frame 110, a lid 101, and a seat 200 alsosupported by the frame 110. In a preferred embodiment, the seat 200 issupported by two sets of seat actuators 111, 112, and 113. In otherembodiments, the number and arrangement of actuators may vary.

In a preferred embodiment, a pair of first seat actuators 111 arepivotally connected to a front area of the seat 200 and a pair of secondseat actuators 112 are pivotally connected to a back area of the seat200 providing support at four “corners” of the seat 200. The four seatactuators 111 and 112 are also pivotally attached to the frame 110. Anadditional pair of third seat actuators 113 are pivotally attached tothe frame 110 at one end and pivotally attached to the second pair ofseat actuators 112 at their other end. In another embodiment, the thirdseat actuators 113 are attached to the first pair of seat actuators 111.

FIG. 3 shows the toilet 100 with the seat 200 fully lowered to justabove the top of the bowl 300. FIG. 4 shows the seat 200 adjusted to agreater height. This allows the seat to be adjusted for a variety ofusers from small children to tall adults.

Referring to FIG. 5, a bowl lift mechanism is used to elevate the bowlthat includes at least one bowl actuator 301. In preferred embodiments,the shroud 400 adapts to changes to the position of the bowl. In such anembodiment, the bowl may remain in fluid connection with the drain ormay be closed off until it is lowered again. In some embodiments, thetoilet may be lowered into the floor to create more space for thetoilet's internal components. In preferred embodiments, the shroud 400is made from an elastic material that stretches and contracts back intoits original shape.

Referring to FIG. 6, an exemplary embodiment of a flexible tube 310 isillustrated in a lowered position. It is made of a series of rotatablyconnected “macaroni” shaped tubes 311. FIG. 7 shows the same tubing 310in a raised position. The act of raising and lowering the bowl 300 withthe plumbing attached could act as the flushing action. When the bowl300 is lifted the tube 310 is straighter and empties everything into thesewer. When it lowers, it creates the standard p-trap with excess tube.The sections of tube 311 shaped like the “macaroni” could also bemotorized at the joints and comprise at least part of the bowl liftmechanism.

Referring to FIGS. 8 and 8A, an exemplary embodiment of a floatingtoilet seat 200 according to the present disclosure is shown. The seatincludes a rigid seat support 201 covered by a shroud 202. Weightsensors 203 are placed between the seat support 201 and floating cover202. In various other embodiments, the weight sensors may be placed in avariety of places such as under the actuators or under the frame.

In various exemplary embodiments, the toilet continuously measuresweight load on both the seat 200 and the foot platform 120. In apreferred embodiment, the system weighs the user on the foot platform120 prior to the user placing any weight against the seat 200 andrecords that as the user's total weight. In some embodiments, the systemcalculates a user total weight using both the seat weight sensors 203and foot platform weight sensors 121 after the user seated with the seat200 fully lowered. In various exemplary embodiments, the systemcalculates the percentage of user body weight on the foot platform 120.The angle of the seat 200 is limited from raising based on thepercentage of weight on the foot platform 120. This prevents the seat200 from tipping to an angle that will not support the user's weightprior to the user being on their feet.

In accordance with the present disclosure, a design for a seat 200 thatcan be easily added/removed from a toilet, seat topper, seat lifter,etc. is provided. This allows for easier installation of a new seat 200to accommodate upgraded seats and/or seat sensors. Referring to FIG. 9,a powered quick disconnect mechanism is shown. The seat 200 is removedby pressing in on the spring-loaded button 204. This moves thespring-loaded axle 205 out of the seat to allow the seat 200 to beremoved. The electrical connector 206 automatically connects anddisconnects with physical connection. The electrical connector 206comprises a ring connector that maintains electrical connectionthroughout the seat's range of motion. This provides for electricalpower and/or data connections to sensors in the seat.

Referring to FIG. 10, an exemplary embodiment of a toilet with a bowl300 that floats on weight sensors 302 is shown. This design enablesweighing excreta in the bowl 300. In such embodiments, the bowl 300 doesnot support the seat 200, lid 101, or any other components of the toilet100. In various preferred embodiments, the weight sensors 302 arelocated between the bowl actuators 301 (see FIG. 5) and the bowl 300 butmay be located anywhere in the bowl support system (e.g., under the bowlactuators 301). Once a user sits down and urinates and defecates, bothare captured separately. The urine flows to its own receptacle, and thefecal matter sits on a shelf. The weight of the separated waste can bemeasured separately or together. If the weight is measured together, bymeasuring the volume of the urine, and assuming its density is equal tothat of water, you can calculate the portion of the total weight thatthe urine is responsible for and thus calculate the weight of the fecalmatter (all the remaining additional weight). With an additional sensorto estimate the size of the fecal matter, fecal density could beestimated.

In this embodiment, the bowl 300 has two first outlets 305 and 306.Outlet 305 is adapted to receive feces. Outlet 306 is adapted to receiveurine. Isolating and separating feces and urine facilitates preparingsamples for analysis. Valves may be used to prevent exit of excretaprior to weighing. Other embodiments may contain more or fewer outlets.In various exemplary embodiments, any type of weight sensor 302, such aspressure sensors and load cells, may be used to measure bowl weight.

In various exemplary embodiments, the bowl 300 has at least one outletand each outlet is connected separately or together to a sewer line. Thetoilet 100 is connected to the sewer line using a seal that does nottransfer any of the weight to the sewer line (e.g., a wiper seal).

Referring to FIG. 11A, a first exemplary embodiments of a mechanism forsealing the connection between the floating bowl and plumbing drain isshown. A first exemplary embodiment of an annular S-seal 303 maintains agas-tight seal between a bowl outlet and the sewage system withoutproviding any support for the weight of the seat.

Referring to FIG. 11B, a first exemplary embodiments of a mechanism forsealing the connection between the floating bowl and plumbing drain isshown. A second exemplary embodiment of an annular S-seal 304 maintainsa gas-tight seal between a bowl outlet and the sewage system withoutproviding any support for the weight of the seat, i.e. withoutinterfering with weight measure through the bowl weight sensor. Invarious other exemplary embodiments, other non-weight bearing sealingmechanisms such as wiper seals or other sliding seals may be used. Invarious exemplary embodiments, excreta are retained in the system byvalves in the outlets.

Thebowl 300 comprises a feces collecting portion 320 and a urine collectingportion 330 separated by a raised hump 340. As discussed in more detailbelow, various scans or tests may be performed on the feces on theportion 320. In various exemplary embodiments, the bowl 300 includes oneor more water jets to push feces off the portion 320 into feces outlet321. In various preferred exemplary embodiments, the fecal portion 320includes a flat horizontal platform. However, in other embodiments, thefecal portion 320 may be flat or curved (convex or concave) and may behorizontal or slanted.

In various exemplary embodiments, the first feces outlet 321 is in fluidcommunication with a feces receptacle 322. In various exemplaryembodiments, the feces receptacle 322 retains the feces for furthersampling, preparation, and/or testing prior to disposal of the fecesthrough a second feces outlet 323. Samples may be extracted fromunprocessed feces or the feces may be comminuted prior to sampleextraction. Testing may be performed in the feces receptacle 322 orelsewhere. In various exemplary embodiments, the feces receptacle 320 issupported by load cells such that the mass of the feces in thereceptacle may be measured. In various exemplary embodiments, scans ortests are performed on the feces on the platform 320 and/or in thereceptacle 322 to determine one or more properties of the fecesincluding weight, color, consistency, volume, density, content,temperature, pH, size and shape, excretion profile, sounds, and gas orfumes.

In various exemplary embodiments, a known quantity of liquid may beadded to the fecal receptacle 320 such that the feces are submerged. Thetotal volume of feces and liquid is measured to determine the volume offeces (total volume minus added liquid volume) which is then used todetermine fecal density.

In various exemplary embodiments, the first urine outlet 331 is in fluidcommunication with a urine receptacle 332. In some embodiments, theurine is retained in the bowl for initial testing and released into thereceptacle by a valve (not shown) for additional testing.

In various exemplary embodiments, the receptacle 332 is large in itsvertical dimension relative to horizontal dimensions in order tofacilitate gravimetric settling of the urine. In various exemplaryembodiments, the urine receptacle 332 retains the urine for furthersampling, preparation, and/or testing prior to disposal of the urinethrough a second urine outlet 333. Samples may be extracted fromunprocessed urine shortly after urination or after the urine has beenallowed to sit and gravimetrically settle. Testing may be performed inthe urine receptacle 322 or elsewhere. Samples may be extracted from theurine receptacle 322 at various locations (e.g., from the bottom, top,or between) after gravimetric settling has occurred.

In various exemplary embodiments, the urine is tested for a variety ofproperties including volume, flow rate, color, weight, density, content,temperature, clarity, pH, settled gradient, and flow geometry. This maybe done with a variety of sensors or testing methods including MOS, CCD,spectrometers, volume measurement devices, weight sensors, temperaturegauges, chromatographs, mass spectrometers, and gas analyzers.

In other embodiments, the seal may be water-tight orsplash-proof.

In various exemplary embodiments, the inner surface of the lid 3101 mayinclude an ultraviolet light source to disinfect the interior of thebowl.

Referring to FIG. 18, an exemplary embodiment of a toilet bowl 4300 thatincludes a visual display 4301 is shown. The display 4301 may includehealth and wellness data, health and wellness trend indicators, images,and combinations thereof. Data and trends may include alphanumericinformation and color-coded information (e.g., red for negative trendsand green for positive trends). The display 4301 may include images forconveying information or for children (e.g., potty training).

In various exemplary embodiments, urine and feces are separated intodifferent collection basins for independent weighing and/or otheranalysis. In various exemplary embodiments, cameras estimate the volumeof the fecal matter and use the estimated volume to estimate density.

In various exemplary embodiments, the toilet is capable of determiningthe total weight of excreta and the separate weights of solids andliquids. For example, weight may be measured after completion of anexcreta event. Liquids may be allowed to exit the bowl and a new weightmeasurement taken of the remaining solids. The difference in weightprovides the weight of liquid excreta. Alternatively, the urine may bedrained off at a known flow rate or through a flow meter to measureurine volume leaving only solids to be weighed.

In various exemplary embodiments, a default position for the bowl and/orseat may be selected by the user. In such embodiments, the system willreturn to this position after being used by someone with a differentpreferred or optimal position. In various exemplary embodiments, thesmart toilet may be programmed with separate default configurations forchildren and adults.

Preferably, the actuators are controlled by a digital controller thatcoordinates the actions of the actuators to thereby provide a smoothlifting and lower at the desired speed. More preferably, the controlleris programmable, so that users can program the lifting and lowering ofthe seat to their preference. Even more preferably, the toilet includesa user identification module, so that the user is automaticallyidentified as he or she approaches or sits on the toilet.

In accordance with the present disclosure, a smart toilet that includesmechanical, hydraulic, power, and data connections to accommodate acombination of health measuring tools is provided. An electricalconnection to provide power to the health measuring tools is alsoprovided.

In various exemplary embodiments, the smart toilet includes at least onesensor that analyzes imaging data. A processor analyzes the data toattempt to compare the user to known users for identification purposes.If a known user is identified, the position of the bowl and/or seat isautomatically adjusted to the preferred position of the user. If theuser is unknown or does not have a record preferred position, theprocessor analyzes the physical characteristics of the user (e.g.,height, waist height, length of upper and lower legs) and adjusts theposition of the bowl and/or seat accordingly. In some embodiments,facial recognition is used to identify users.

In various preferred embodiments, the system may identify a user basedon their face, hand, or foot. In various preferred embodiments, thesensor may include a CCD (charge-coupled device) or MOS (metal oxidesemiconductor), including CMOS (complementary metal oxidesemiconductor). The sensor can be used, with proper calibration such astaking the data at a known distance, to measure the length of majorbones. This data can then be used to customize the toiler position foran unknown user.

In various exemplary embodiments, the toilet system includes sensors formeasuring the user's weight. This includes separate sensors fordetermining user weight on the seat and user weight on the user's feet.The user's weight that is supported by their feet is preferably measuredusing a platform adjacent to the toilet on which the user's feet areplaced while sitting and while being lowered or raised from the toilet.

In the preferred embodiments, the toilet also includes health assessmentdevices supported by the frame. Examples of such devices include imagingcameras, flow spectrometers, volume measurement devices, body weightsensors, and gas analyzers. Toilets with such devices are described inthe patents and published applications cited in the Background sectionabove.

In various exemplary embodiments, the seat and bowl may be liftedtogether such that the toilet may be used as a urinal. In such aconfiguration, the system may be designed to flush with a reduced volumeof water.

All patents, published patent applications, and other publicationsreferred to herein are incorporated herein by reference. The inventionhas been described with reference to various specific and preferredembodiments and techniques. Nevertheless, it is understood that manyvariations and modifications may be made while remaining within thespirit and scope of the invention.
